IXD3236A15DMR-G application field and working principle

PMIC – Voltage Regulators – DC DC Switching Regulators

The IXD3236A15DMR-G is a high-efficiency, high-speed, synchronous DC-DC buck converter designed specifically for mobile device applications. This high-performance device combines superior power conversion with good thermal performance, enabling the design of cost-effective, high-temperature applications. The device has an integrated quasi-resonant (QR) architecture, enabling frequences up to 1MHz and device cycle times as low as several hundred nanoseconds. The IXD3236A15DMR-G is qualified for use in a wide range of mobile applications, including smartphones, tablets, laptops, and portable gaming devices.

The IXD3236A15DMR-G is capable of delivering up to 5A of output current with a maximum input voltage of 20V. It has a programmable voltage range of 0.8V to 16V, allowing for precise regulation of the output voltage. Additionally, the device has a low dropout voltage, allowing it to operate efficiently even at low input voltages. The device also features integrated short-circuit protection, over-current protection, and over-temperature protection to help protect your system against damage or degradation.

The IXD3236A15DMR-G’s uses a synchronous rectification scheme with controlled on-time to achieve high efficiency. The device incorporates a step-down boost converter and an active-clamp PWM controller. The boost converter increases the voltage on its output stage, which is then used to drive the PWM controller. The controller in turn drives the transistors in the synchronous rectification scheme, which regulate the output voltage. The controller continuously monitors the output voltage and adjusts the on-time of the transistors to ensure that it remains within the desired range.

The IXD3236A15DMR-G also features a range of protection features that ensure safe and reliable operation. For example, the device has an adjustable over-voltage protection that prevents the output voltage from exceeding its upper limit, as well as adjustable over-current protection that prevents the output current from exceeding its upper limit. The device also has a thermal protection feature that will shut down the regulator if its temperature exceeds a certain limit, preventing damage to the device or other components in the system.

In summary, the IXD3236A15DMR-G is an advanced, high-efficiency, high-speed, synchronous DC-DC buck converter designed specifically for mobile device applications. Its high efficiency and precise regulation of the output voltage, combined with integrated protection features, make it an ideal choice for cost-effective, high-temperature applications.
